is the result of intensive work in research and the experience
Its design,
based on a control system with an intelligent microprocessor
provides the user with easy-to-use advanced features. The digital control system allows the user to make most of the necessary operations automatic in order to optimize the measurement process; for example, c ontinuous frequency
synthesis
correction of linearity and flatness errors, the proper selection of attenuators and automatic cut-off if the instrument remains inactive for a c ertain period of time. To enhance its features, it allows a plan of up to 239 channels.
Its accuracy and reliability satisfy the requirements of the most demanding users.
,
,
The signal level measured is shown numerically on an LCD display in absolute values. It is also equipped with a
computer connection
which allows one to
personalize the configuration of the instrument.
The instrument is powered by an external rechargeable battery and it is safe to use outdoors.
The implementation of all these functions in an instrument weighing only half a kilo, makes the
PROMAX-6
an incomparable work tool.
Every detail has been carefully studied to achieve the best possible balance between its features and its operability. The result is an easy-to-handle piece of equipment with advanced functions, which may be used ev en by non-specialized personnel.

The
is an portable instrument powered by a built-in 7.2 V NiCd rechargeable battery. Before taking any measurement, the user should m ake sure that the battery is fully charged (use the charge/discharge charger supplied with the instrume nt).
3.1.1 Recharging the battery
The battery charger has an automatic safety circuit to prevent any possible
damage to the unit as a result of defective batteries.
The instrument is equipped with a 230 V / 50-60 Hz m ains adaptor for Europe and other countries to power the battery charger. (See accessories to place an order for other types of adapters.)
1) Connect the cable from the mains adapter to the charger. Connect the

in order to eliminate any possible residual charge. In order to do so, press button A situated on the right (see figure 1). At this point, a small yellow light com es on and the process of discharging is under way. When discharging is completed, the charger automatically sets the process of charging underway.
3) The
charging process
lasts for two and a half hours. When the process is completed, the three red indicators will light up. At the same time, an indicator will flash and an acoustic alarm will sound for 90 seconds, indicating that the charging process has been successfully completed.
4) After this period, if the battery is not removed from the charger it will remain in permanent
minimum char g e mode.
A green LED will flash until the battery
is removed.
CAUTION
1) Before using the charger, make sure that the adapter is suitable for the ma ins volta g e . A n in dica to r will light u p wh e n the a da p te r is c onnecte d to the ma ins and the cha rger is conne cted.
2) This charger is de signed for cha rging Ni-C d ba tteries.
3) In order to prolong the lifetime of the batteries, it is advisable not to remove it from the ch a rge r wh ile the ch a rging proc e ss is still unde r way.
4) The ma ins a dapte r and the ba ttery cha rger a re de signed for indoor use.
5) When using the batte ry first time, it is advisable to carry out two charging and discha rging processes into the charger itself, in order to e liminate any possible memory effect, accumulated during the period it has been in storage.

Installation of the CB-038 battery.
The battery is accessible from the back of the instrument. To disconnect the battery, press the tab found at one end of it (1) and move the battery to separate it from the body of the instrument (2). The battery will be released from its holder. Then slide the battery out, as shown in figure 3.

3.3 Installation and start-up
PROMAX-6
The battery is installed and the instrument is connected, the version of the instrument and the channel plan which it has stored will appear on the display for a few moments.
When this indication appears, the instrument is in channel tuning mode. By means of the program RM-006, one c an select the starting up of the instrument in one of the three tuning modes: FREQ or CHAN.
When the ON/OFF key [12] is pressed, the instrument is then in "automatic cut­off" mode; in other words, the device is automatically disconnected when twelve minutes in operation have gone by without a key being pressed.
The automatic cut-off mode c an be deactivated by holding down the ON/O FF key for one or two seconds when the device is connected. The indicator "manual power off" will appear on the display.

If the battery is low (at a voltage of less than 6.5 V ), a blinking message will appear on the display [3]. When the v oltage is lower than 6.0 V, the instrument disconnects.
A fully charged battery can power the equipment non-stop for more than an hour and a half. At 30% stop/start of intermittent operation, the battery can power it for up to five hours. When the LOW BATTERY indicator appears, the battery must be recharged.
When a fully discharged battery is installed, it is possible that, due to residual charges, the automatically disconnect before the message LOW BATTERY appears on the display.
